## Customer Reviews

### ⭐⭐⭐⭐⭐ Computar Lenses
*by C***Y on November 11, 2011*

I have purchased several of these in the past. All of them have performed flawlessly. They are manual iris, so it does take a bit of tweaking to find the happy medium for light level if your using these in an outdoor application. Once adjusted properly, they produce a crystal clear and sharp image. Currently using with a Trendnet IP cameras.

### ⭐⭐⭐⭐⭐ Great Product
*by H***N on August 27, 2012*

Great price and great image quality. Works with both my analog 700 TV line cameras and with my trendnet 1.3 megapixel IP camera.
